The nozzle itself is a normally closed valve (normally closed valve
means that when there is no input control signal, the valve is
always closed; Normally open valve is when there is no input
control signal, the valve is always in the open state), by a valve
needle up and down to control the valve opening and closing. When
the ECU gives the injection command, its voltage signal causes the
current to flow through the coil in the nozzle, creating a magnetic
field to pull up the valve needle and open the valve so that the
oil can be sprayed out of the injection hole. The biggest advantage
of injection fuel supply is that the control of fuel supply is very
precise, so that the engine can have the correct air-fuel ratio in
any state, not only to keep the engine running smoothly, but also
to comply with environmental regulations.
The working quality of the fuel injection nozzle plays a
fundamental role in the power of each engine. Due to poor fuel, the
fuel injection nozzle does not work well, causing serious carbon
accumulation in the cylinder; Cylinder, piston ring accelerated
wear, resulting in unstable idle speed, fuel consumption rise, weak
acceleration, starting difficulties and excessive emissions,
serious will completely block the nozzle, damage the engine.
Therefore, the nozzle should be cleaned regularly, and long-term
cleaning or frequent cleaning of the nozzle will cause bad effects.
